Life history of H. sosybius

Its larvae can feed upon the highly-invasive Japanese stilt grass Microstegium vimineum,[4] so populations of this butterfly are potentially at risk from efforts to remove stilt grass. The endangered Mitchell's Satyr Neonympha mitchellii is also able to feed upon stilt grass.[5][6]

The larvae also feed on various Poaceae species, including Axonopus compressus, Eremochloa ophiuroides, Stenotaphrum secundatum and Poa pratensis.
